The spherical dusty coma of erupting Comet 17P/Holmes nearly fills the 11.5x8.6 arcminute field of view. The nucleus is the brightest star-like object in the image. A secondary bright and also spherical region is SW of the nucleus. The two stars below the nucleus are 10.89 and 9.25 magnitude. To the unaided eye at the time this image was taken Holmes appeared to be about 3rd magnitude.
